IMPROVEMENT IN CLAY-PIPE MACHINES.

TO ALL WHOM IT MAY CONOERN:

Be it known that I, GEORGE D. GOODRICH, of the city of Joliet, in thecounty of Will, and State of Illinois, have invented certain new anduseful Improvements in Machinery for the Manufacture of Clay Pipes; andI do hereby declare that the following is a full, clear, and exact.description thereof, reference being had to the accompanying drawingsof two sheets, forming a part of thisspecitication, in which- Figure 1is a side view with a portion of one of the posts removed.

The nature and object of my invention consist in constructing u seriesof machinery to be used in ther manufacture of clay pipes for draintile, sewer pipes, Src., so that the operation will -be continuous fromthe time the clay is forced through the mould until the same trough isreturned to receive a section of pipe, and the pipe cut intoproperlengths or sections from a mould 'through which the pipe ispassed-continuously; in providing such machinery with an improvedplatform for receiving-the pipe from the mould into the receivingtrough; in providing a wheel to operate the sliding-shaft and'cutter; inprovidinga sliding-bar below such platform with stops to regulate andadjust the lengths of the section of pipe; in providing such wheel andsliding-bar with cams and spring; in providing the wheel with armsextending beyond and the entire length of the receiving platform towhich the cutting wiresare attached; in constructing and providing anelevator i at the side of the receiving platform, and operating at theside of asingle post or standard to receive and elevate the trough andpipe; in the peculiar arrangement and construction'of such elevator; inproviding such postV or elevator with an automatic stop and rest; iu thepeculiar construction of such rest; in providing the operating shaftwith a cylinder operated by a lever-spring catch and conical orwedge-shaped retractor; in providing such machinery with a postorstanda-rd, having guides on the side to guide the dumping platform inproviding dumping platforms, one of which will operate the other in thepeculiar construction of such dumping platform in providing a. platformto receive the empty troughs from such dumping apparatus, and in theseveral combina- "tions hereinafter set forth and claimed as new.

To enable other skilled in the art to make and use my invention and myimproved machinery, l will proceed to describe its construction andoperation. Y Y

It is designed to use this machinery in a two-story building, in whichevent A1 will represent the first door, and Az the second, and the postsof the frameA will represent the walls or supports of the building. In aonestory building thc frame A will be made in any convenient manner. Themould is not represented, but the -pipe is discharged from the mouldthrough the standard or post, B, on tothe sliding support, C, which willslide upon the arms j so as to occupy a portion of the space between thepost- B and the trough O. I attach a post, H, to the floor, opposite thepost 13, at a. suitable distance therefrom; and at a proper distanceabove the floor to give the arms of the cutter a free movement I inserta bar or shaft, J. 'llo this shaft I attach the wheel I and collar b, ofthe cutter and the lo'wer arms or timbers of the carrying device. Thesearms, L, areiprovided on each side with screws, a rt, upon which thecross-bars t and m rest, and by means ot' which the height of the frameis adjusted to adapt itto the size of the pipe passing into the troughO. To these cross-bars m and on I attach wheels or rollers, 'l,which'extend beyond the bar m, and arc provided with flanges at each endto keep the movable platform N', (more fully shown at tig. 13,) inposition. Cross-timbers or bars, H', supporting the crosswheels orrollers. yu., are placed upon the bars m.. The rollers 11 are alsoprovided with Hanges, and project slightly above the movable platformN'. Upon these c1ossrollei's the trough is placed, as shown. To theshaft attach a slidingfbar, K, at the upper side this shaft at the outerend it may he attached to C by z', or left, as .own; and naar this'posses under the collar b of the cutter; at the other end the arms orstops dare attached. heee arms d project upwardssuiiciently to stop thefriction of the pipe from carrying the trough O over-thi rame, und theshaft is secured in place by passing under the rim of the circular band,Z, of the wheel I, (figsv 1.5 and 17.) 'llo the sides, of this bar J lattach a spring, g, (tig. 17,) which is provided with a'hook, fz, whidhoperates on a catch, 1.', which is attached to the sliding-bar K, and isunhooked by the camsfk of the plate l of the wheel l. To the wheel l areattached arms, c c, at Vopposite sides, which are extended far enough toallow the lient portion to pass entirely around the receiving frame ordevice, and are long enough to pass beyond said frame. To thebent'portion of these arms l attach small \vires,'ff, at their outerends, and at vthe inner ends they are attached to the Wheel l and thecollar in any-convenient manner. 'lhcse wires are placed so as to comevery near the ends of the trough 0, and' by giving the wheel l a halfrevolution, cut the continuous pipe into proper lengths or sections,when it is ready to bc removed and elevated to the upper floor. For lthepurpose of elevating it I attach to the side ofthe standard or post D,which has a T-shapcd groove or guide, Z', 'which guides the head P ofthc elevator. This. lread ('gs. 4, 5, and 6,) is made of suicient lengthto keep it steady and prevent bending on the guide, and on each side isa. projection, .which has'an upper and lower cam, o and n, .and to itsfront is attached a plate, m', which is provided' with arms, Il, thatare carried outfand bent to receive the ends of the ytrough O. At theupper end of the head l? thercis an eye orloop attached, into which thecord, @,is fastened; a similar one is made at the lower end to attach aweight if necessary.' At a proper distance above the second door or topof the framabeut arms', W, (liga. l, 2and 3,) are hinged' to the sidesof the pgst D, so as to stand over the bent` arms l Z. The ends 'ofthese arms are extended through the post D into the guide cavity Z, soas to he operated by the 'cams n and o at the sidesV of the elevatorhead l. They are also provided with springs, 2, to throw them under thetrough O assoon as ithasbcen elevated to the required height. Thesesprings, in the form of attachment shown, at their outer ends restVagainst pendent projections attached to the bent arms, but may beapplied directly tothe back of the arms',or in any convenient manner,the design being to malte the arms work automatically, so that theattendant will not need to he alivays at this point. To complete theautomatic Working I attach to a driving-shaft, Q, a small head, z,permanently, and .fi-cylinder, R, loosely. This cylinder is slid` uponthe shaft by means of the lever w, and when brought against the, head :cit is held by friction or proper clutches, and secured hy the spring u,which is provided -With a stop, y, (figs. l and 4,) that rests againstthe upper end of the lever w. A cord, q, is attached to this'cylinderand passes up over a sleeve or pulley on the top of the post S, and overto a similar one at the top of the post D, and down to the head P of theelevator. '.loA this oord attach a conical block, t, which is attachedto the cord at such a distance from the springV u as that when theelevator passes the bent arms w, this block will press the spring andrelease it from the lever w, so that the cylinder R will cease revolvingwith the shaft, and'the elevator commence descending. The upper end ofthe lever w is made wide enough for the stop y of the spring u to rest'against it in, order to prevent the conical block from catching in itsascent. The empty troughs are lowered by means of the apparatus attachedto the shaft E, shown at figs. 1, '.7, 8, 9, and 10. This standard orpost is provided on bpposite sides with T-shaped grooves or guides, Z,similar to that in post l). The top of this post is provided withcross-bars, t" i', which support the frictionuollers g g', over whichpasses the cord a', which supports at each dnd a dumping frame, only oneof whichfis shown, but both are made alike, and a description ofcne willapply tofbrth. The head h is fitted to the interior of the guide grooveZ, andhas a projection at its front to which the upper end of the arm Yis hinged. .This arm is also bent, and is of suflicient length to passover and to the bottom of aftrough, where its lower end is hinged to aprojection, e', of the bottom X.' The bottom X has eyes or loops at eachend, and lateral projectionspm, at the inside, which are fitted to thesides of the post E. bail, b', bent in the form shown in figs. l and 9,is attached at the eyes e to the bottom, and at .the upper end to thecord a. This cord a passes over and around the rollers or pulley g andunder. the friction clutch c, (iig. 8,),and is provided with a swelledor double conical block,'f, which operates the friction clutch d', whichis also double acting. Thel object of this is to check the motion of thedumping frame in its descent, so that the empty troughslwill not beprecipitated upon the platform F withtoo much force and injure thetroughs. When the bottom X passes .below the end of the post E, itswings under the end of said post, when it will turn upon the bail laand dump the trough; the block f should therefore be so located that itwill strike the friction clutch just before the bottom X passes belowthe end of the post, and being double acting only one will be requiredforbcth frames, but if desired it can be duplicated and pla-ced on bothsides. A. dumping platform F, provided with rollers v, is placed belowthe end of the standard or post E, te receive the empty troughs as theyl escend. The rollers v are placed on the same plane as the `upperrollers u of the receiving frame. This platform is'supported in positionby any convenient method. The sizes of' the several posts of mymachinery will be governed by the length of the sections of clay pipe tobe made, and by the material used in its construction, as it can nearlyall be made of wood, or may be economically made principally of iron.Ordinary sections of pipe weigh from forty to about one hundred andtwenty pounds in the trough, so that a strength of parts which willsustain a Weight of two hundred pounds iivill be sullicient.

The `operation is as follows: The ground or prepared clay is forced at 1Ifrom the mould through the post` B into the sliding rest c whichslideson its arms j', about half-way from the .post to the trough, andshould be located about one-eighth of one inch higher than the trough Oit then passes into and through the trough, which4 is prevented fromsliding or rolling back bythe stops a, which are held and locked by thesprings g. When the pipe has passed'through the trough the attendantthen takes hold of the arm e and gives the Wheel I a half revolution,which fmotioucauses the wiresfto pass through the pipe and cut it atboth ends, and also releases the spring catch g k by means of the cams kand the stops d, when the trough is rolled back till the Acircularcavities nf' are directly over the rollers u, which lets the trough downon to the platform'li which rests upon the rollers T, when it'is pushedwith N down to the post D, 'which brings the trough over the arms Z. Thecylinder R is then thrown into gear and it is taken up on the-elevator;platformN is immediately returned to its position,`

another trough taken from, platform F and rolled to the same place whichthe other occupied. When the head? of the elevator reaches the points 7:of the arms w, the cams o, pressing against the back of the points fc',open the arms'and allow the 4trough to pass through, and the springs zwill return them as soon as the trough passes them, or the points r passthe lower end of P g and to ensure their perfect Working, the cams natthe lower end of the head block Pstrike against'the front of thepoints 7c and force them under suiliciently by its weight indescending., A'ssoon as the head block is'pa'st the points la', theblockt on the cord strikes the spring u and releases the cylinder R, whenthe' elevator will descend, leaving the trough on the spring arms zuthis is necessary, as it would require an additional attendant if thispart did not work automatically. The trough is then taken and emptied,when it is thrown on to the platform X, where its Weight causes itto-descend. The

peculiar construction and method of hanging this platform causes it tovkeep nearly horizontal until it `passes the bottom ofthe post, when itwill cant and slide the trough ol into platform F, when it is ready tobe used again, and the friction clutch d with the conical block j willbreak the'force of the descent so that it will be landed without injury.I use five of the troughs O in, operating the machinery, and whencomplete .will be found-very useful in the manufacture of clay pipes,where the pipe is made continuous and in ahorizcntal position.
